ABSTRACT
AIM: The study was a methodological conducted to evaluate the validity and reliability of the Turkish version of the Diabetes Caregiver Activity and Support Scale (D-CASS). METHODS: This study was included on 272 individuals who cared for patients diagnosed with type 2 diabetes at least one year ago. Language, content, internal criterion, construct-concept validity were used to test the validity of the scale, and cronbach alpha, item-scale correlation, and test-retest were used to test the reliability. RESULTS: The CVI was 0.95. The study was conducted with 272(60.3% female, 39.7% male) caregivers of individuals with type 2 diabetes. The study was found four week test-retest reliability with r = 0.70, p < 0001. The factor loadings of the scale items are between 0.77 and 0.95. The single factor obtained explains 75% of the total variance. The scale was found to have a high degree of reliability (Cronbach alpha=0.95). CONCLUSION: The activities and supportive behaviours scale of caregivers of individuals with type 2 diabetes(D-CASS) is a valid and reliable measurement tool that can be used for the Turkish population.
